>If you turn on your electric stove at 3pm, when the grid is stressed from the afternoon sun, your electricity is almost certainly coming from a peaker plant (unless you're in California, at which point the peaker-plants are coming on at 6pm or so). For California, you can check the actual generation mix: https://www.caiso.com/TodaysOutlook/Pages/supply.html https://www.caiso.com/TodaysOutlook/Pages/supply.html For today: | MW @ 2AM | MW @ 3PM ------------+----------+--------- Renewables | 5337 | 17228 Natural Gas | 10339 | 9568 Hydro | 1529 | 1178 Imports | 6216 | 778 Batteries | -23 | 183 Nuclear | 2241 | 2240 Coal | 7 | 2 ...so at 3PM ~31% of your electricity was produced by natural gas, and at 2AM ~40% of your power was produced by natural gas.
